摘要
以郑少高速公路甄坟沟大桥为工程背景,考虑分体式箱梁桥简支转连续施工过程的横向整体与纵向整体2类(8种)施工方案,利用有限元软件MIDAS/Civil建立全桥空间有限元计算模型,分别对2类(8种)施工方案的施工工序进行施工过程仿真分析。计算结果表明:从简支转连续施工过程中的主梁结构内力变化考虑,横向整体施工方案优于纵向整体施工方案,并且横向整体施工方案中先两端后中间的纵向连接工序(横C)为最优施工顺序。
Against the background of the Zhenfengou Bridge on Zhengzhou-Shaolin Temple Expressway and in consideration of two types(8 kinds) of the construction schemes of transverse integrity and longitudinal integrity used in the construction process of transferring the simply-supported structure to the continuous one for a separated box girder bridge,this paper establishes the spatial finite element calculation model for the whole bridge of such type of the bridge,using the software MIDAS/Civil and respectively con...
